DETAILED DESCRIPTION

U.S. Provisional Application 62/055,292 of filing date Sep. 25, 2014 is hereby incorporated herein by reference.

The long haul trucking and container industries are the backbone of nearly all intermodal transportation worldwide. Nearly all cargo transported is done so using one of these two methods.

With regards to the trucking industry, a considerable amount of time and money is spent transporting empty semi-trailers either back to their original location, or to a different location to be reloaded or swapped out for a different type of trailer to handle a different type of cargo. The lack of versatility in the use of a single trailer fails to meet the growing desire for complete intermodalization within the industry.

The ability to collapse a cargo trailer into a flatbed will increase the flexibility of the of the company operating the trailer. Types of cargoes that would require a flatbed trailer may now be transported on the same trailer, reducing the need for purchasing and operating multiple types of trailers by the operators. The concept of the collapsing trailer allows for owners to move multiple empty trailers across the country, with greater storage flexibility and lower overall cost in terms of fuel and miles traveled. In addition the reduction in air drag by converting an empty semi-trailer into a flatbed when the trailer must be transported empty will reduce fuel consumption costs. The ability to stack containers and/or trailers will reduce consumption of valuable space in storage yards.

In one set of examples, disclosed is a vertically collapsible semi-truck trailer for towing by a semi-truck cab, with four sides, a cargo bed floor, a cargo trailer roof/flatbed floor, and a mechanical lifting mechanism. The long side walls roll to open or close the sides (in one example, they roll upward into a box at the top of the trailer box; in another example, they roll downward into a box at the bottom of the trailer box). In one example, the walls dispose into a receptacle or similar storage space. The rear door and forward end roll upward into a horizontal track (in one example they fold inwards using hinges and joints). The remaining frame collapses inward to allow the cargo trailer roof to become the flatbed floor. The mechanical lifting mechanism in the side walls control the lowering of the top frame of the trailer (as, or after, the side walls have been rolled and the end walls have rolled upwards).

In one example of the self-erecting collapsible container portion, the container conforms to international standards of size, shape and weight requirements set forth for shipping containers. In one example, the container conforms to International Organization for Standardization (ISO) ISO 668 (2013) series 1 freight containers for classification dimensions and ratings. In one example, lengths of containers vary from 8 to 56 feet (2.438 to 17.069 meters) and heights from 8 feet (2.438 meters) to 9 feet 6 inches (2.896 m). In one example, the container conforms to International Organization for Standardization (ISO) ISO 668 (2013) for classification, dimensions and ratings of intermodal shipping containers. In one example, the container conforms to International Organization for Standardization (ISO) ISO 6346 (1995) for coding, identification and marking of intermodal shipping containers. In one example of the self-erecting collapsible container the frame assembly is attached to a trailer assembly meeting the standards set forth by the trucking regulatory agency in which the trailer is operating. A division of the U.S. Department of Transportation (DOT), the Federal Motor Carrier Safety Administration (FMCSA) regulates nearly all aspects of the trucking industry including length, width, and height limits. At present, there is no federal height limit, and states may set their own limits which range from 13 feet 6 inches (4.11 m) (mostly on the east coast) to 14 feet (4.3 m) (west coast). As a result, the majority of trucks are somewhere between 13 feet 6 inches (4.11 m) and 14 feet (4.3 m) high. The Federal Bridge Gross Weight Formula (also known as Bridge Formula B and the Federal Bridge Formula) dictates that the federal gross weight limit for a Class 8 truck is 80,000 pounds (36,000 kg) (combined weight of truck, trailer, and cargo). In one example of the self-erecting collapsible container portion, the container conforms to United States or individual State standards of size, shape and weight requirements set forth for shipping containers. In one example of the self-erecting collapsible container portion, the container conforms to Mexico standards of size, shape and weight requirements set forth for shipping containers. In one example of the self-erecting collapsible container portion, the container conforms to Canada standards of size, shape and weight requirements set forth for shipping containers. In one example of the self-erecting collapsible container portion, the container conforms to the standards of size, shape and weight requirements set forth for shipping containers for the country where the container will be used.

In one example, also included is one or more vertical height locking mechanisms to relieve the scissor jack when in the (full-vertical) extended position.

In one example, the top/roof of the collapsible semi-truck trailer has one or more risible “nubs” or risible twist locks to receive bottom sockets of a shipping container (enabling a shipping container to ride on top of the collapsed flat bed and locked in place).

In one example, sockets for twist locks to receive shipping containers are also disposed on the top/roof of the collapsible semi-truck trailer. In one example, the top member is pre-engineered to receive at least one additional frame assembly, in one example, of another container or collapsible container disposed on the top.

In one alternate example, the end walls fold inward instead of rolling inwards.

In one alternate example, the disclosure herein is used for constructing collapsible shipping containers instead of collapsible semi-truck trailers having a collapsible container portion.

In one alternate example, the disclosure herein is used for constructing collapsible Box trucks instead of collapsible semi-truck trailers.

In one alternate example, the disclosure herein is used for constructing collapsible rail cars instead of collapsible semi-truck trailers.

In one alternate example, the disclosure herein is used for constructing small personal trailers for towing behind personal vehicles instead of collapsible semi-truck trailers.

In one example, the mechanical lifting mechanism is a hydraulic arm or any other type of mechanical lifting device instead of a scissor lift system. In one example, the motor that operates the mechanical lifting mechanism is located outside the trailer. In one example, the motor that operates the mechanical lifting mechanism is located underneath the trailer. In one example, a barrier separates the enclosing cargo space from the mechanical lifting mechanism. In one example, the mechanical lifting mechanism is operated manually with a hand crank or other similar device.

FIG. 1 illustrates a side view of an example of the vertically collapsible trailer 1 in extended position, with near side wall cut-away to show interior mechanism. In this FIG. 1, the nearest one of two retractable sidewalls 6 is removed (cut-away) to enable illustration of the interior of far sidewall 6 and enclosing cargo space 1018.

In one example, the cargo space is a weather tight area in which the cargo being shipped is contained. In one example, this area is surrounded by two side walls, a forward wall, an after door and a trailer roof. In one example, when in the collapsed position, this area is inaccessible and weather tight. In one example, a folding portion of the frame on the after end of the trailer folds inwards as the trailer goes to the collapsed position.

In one example, a long sidewall is disposed on one or both sides of the container/trailer which, in one example, utilizes a slatted wall which can roll either, in one example, upwards or, in one example, downwards into a barrel. In one example, the collapsed position the side wall will be completely retracted into the rolling barrel.

In one example, integrated into trailer 1 is a self-erecting collapsible container, the container having: a frame assembly including a plurality of frame members 2, 3 having a longitudinal length and a width; and a plurality of articulated vertical frame members 9, 10 disposed between the rectangular frame members 2, 3; where at least one rectangular frame member 3 comprises a receptacle member 61 in the length direction (shown in FIG. 11); where at least one rectangular frame member comprises a receptacle member 71, 81 in the width direction; where the articulated vertical frame members 9, 10 are positioned and arranged to retract to within the frame assembly; a lifting mechanism 4 is positioned and arranged to elevate the rectangular frame members 2, 3 from each other; a retractable side wall 6 is positioned and arranged to retract into the receptacle member in the length direction; a retractable end wall 7, 8 positioned and arranged to retract into the receptacle member 71, 81 in the width direction (shown in FIG. 12); a top member 31 disposed on an uppermost rectangular frame member 3 of the frame assembly; a bottom member 21 disposed on a lowermost rectangular frame member 2 of the frame assembly.

In one example, rectangular frame members 2, 3 are horizontally disposed relative to vertical frame members 9, 10 when frame members 9, 10 are in the extended (elevated, non-retracted) vertical position.

In one example, frame member 2 integrates with a trailer, providing support of the entire trailer and connecting the major components together for supporting the weight of the cargo. In one example, the frame assembly meets the standards of the trucking regulatory agency in which the trailer is being operated as well as being able to support the weight a standard trailer or flatbed trailer would typically support. In one example, bottom member 21 includes a floor of the internal cargo space which, in one example, will support the cargo stored while the trailer is being used in the expanded mode. In one example, while the trailer is in the collapsed mode this floor will be inaccessible.

In this example, retractable end wall 7 and articulated vertical frame member 9 are positioned at the longitudinal rear end of trailer 1. Retractable end wall 8 and articulated vertical frame member 10 are positioned at the longitudinal front end of trailer 1. Rear retractable end wall 7 retracts into receptacle member 71. In like manner, rear retractable end wall 8 retracts into receptacle member 81. Therefore, in one example, a portion of the trailer either or both fore and aft allows for the entrance of the rolling end wall into an upper portion of the cargo space along, in one example, horizontal tracks.

In one example, tracks are located on either side of the trailer body in which the after rolling door and forward rolling wall can run along to conceal them. In one example, a rolling track entrance is provided, opening into an area where the rolling door bends, in one example, into the horizontal tracks along the top of the cargo space.

In one example of a retractable forward end wall, a rolling wall secures the forward end of the cargo space when the trailer is in the raised position. In one example, this is achieved with an upward rolling door either, in one example, into a barrel or, in one example, into horizontal tracks along the underside of the trailer roof. In one example, this is achieved with an inward folding door. In one example of the self-erecting collapsible container, the end walls are positioned and arranged to fold in the inward direction. In one example, doors that fold inwards comprise a series of hinged panels. In one example, a refrigeration or air conditioning unit is attached to (or, in one example capable of being attached to) this panel for a climate-controlled trailer.

In one example, the after end of the cargo trailer is made up of two non-folding portions of the rear door. In one example, this connection is weatherproof and the cargo space will not be accessible in the collapsed position.

An enclosing cargo space 1018 is formed with lifting mechanism 4 in the extended position, elevating rectangular frame members 2, 3 from each other.

In one example, also included is a locking mechanism to lock the frame assembly in place when in the collapsed position. In one example, the locking mechanism is attached to the lower frame. In one example, the locking mechanism is also a support for the frame in the collapsed position. In one example, the locking mechanism is attached to the upper most frame or, in one example, the vertical frames or, in one example, the lifting mechanism. In one example, a locking mechanism is provided to prevent the rolling walls or, in one example, the rolling end walls to prevent them from unrolling when in the collapsed position. In one example, at least one lock member is disposed on the uppermost rectangular frame member. In one example, at least one lock member is disposed on at least one of the plurality of articulated vertical frame members. In one example, at least one lock member is positioned and arranged to lock the retractable side wall in place when the frame assembly is in a collapsed position. In one example, the at least one lock member is disposed on the retractable side wall. In one example, a mechanical locking mechanism is included for the trailer to keep it in the collapsed position. This locking mechanism, in one example, is disposed elsewhere on the trailer. In one example, the locking mechanism for the frame is operated mechanically or manually. In one example, the locking mechanism is operated manually. In one example, the locking mechanism is automatic. In one example, the locking mechanism is operable either manually or automatically.

In one example of the self-erecting collapsible container, a vertical height locking member is positioned and arranged to immobilize at least one of the plurality of articulated vertical frame members when the articulated vertical frame members are in a fully extended vertical position. In one example, the locking member is attached in the middle of the folding frames or, in one example, at the top or, in one example, located in the lifting mechanism itself. In one example, the locking mechanism is operated manually. In one example, the locking mechanism is automatic. In one example, the locking mechanism is operable either manually or automatically.

In one example, locking mechanisms 1012 serve to removably affix the rectangular frame members 2, 3 to each other when in the collapsed position. In one example, a mechanical locking mechanism is provided for the trailer to keep it in the collapsed position. In one example, a locking mechanism is provided for the frame which can either be operated mechanically or manually. In one example, locking mechanisms 1012 provide compressive strength to support frame member 3 resting over frame member 2. This locking mechanism, in one example, is a manual mechanism located elsewhere on the trailer. Vertical frame bottom hinge 102 enables articulation of the articulated vertical frame members 9, 10. In one example where more than two rectangular frame members are used, locking mechanisms are disposed to removably affix one or more pairs of rectangular frame members.

In the example as illustrated, both front and rear end walls 7, 8 have corresponding receptacles 71, 81 for stowage. In one example, the receptacles include an area where the rolling door bends, in one example, into horizontal tracks along the top of the cargo space. In other examples, one or more end or side walls are fixed and do not use a stowage receptacle. In one example, tracks are located on either side of the trailer body in which the after rolling door and forward rolling wall can run along to conceal them.

In one example, the end wall includes a rolling door that allows access to the cargo space when the trailer is in the raised position. In one example, the rear portion of flatbed trailer, in the collapsed position, is approximately one fourth the size of the expanded unit. In one example, the collapsed rear portion is made up of two non-folded portions of the rear door, which seal the cargo space from weather.

Other components are shown in the illustrated example of FIG. 1 to show relative positioning and arrangement of the trailer-container components in the example where a trailer assembly or trailer components are combined with the collapsible container cargo space. Rear Tires and Tandem Axle 1006 are disposed under frame 2 toward the longitudinal rear portion of the container. In one example, the rear axle and components connect the tires to the frame of the trailer. In one example, the tire and axle combination meets the standards of the trucking regulatory agency in which the trailer is being operated as well as be able to support the weight that a standard trailer or flatbed trailer could support. Landing gear 1010 is disposed under frame 2 toward the longitudinal front third portion of the trailer. In one example, the landing gear are extendable legs for the trailer to be supported when not connected to a truck. In one example, the landing gear meet the standards of the trucking regulatory agency in which the trailer is being operated. A king pin 1014 is shown disposed under frame 2, further towards the front portion of the trailer from landing gear 1010. In one example, king pin 1014 is a nipple at the front of the trailer to connect to a fifth wheel coupling on the tractor unit. In one example, king pin 1014 meets the standards of the trucking regulatory agency in which the trailer is being operated.

A spare tire compartment 1008 is disposed under frame 2, midway between rear tires 1006 and landing gear 1010. In one example, the compartment meets the standards of the trucking regulatory agency in which the trailer is being operated. A rear bumper 1004 is disposed on the longitudinal rear end of the container-trailer combination. In one example, a rear portion of the trailer frame contains the lights and reflection materials, as well as any other components required to meet the standards of the trucking regulatory agency in which the trailer is being operated. A port 1016 for electrical and air connections are disposed on the longitudinal front end of the container-trailer combination.

In further examples, it can be appreciated that the vertically collapsible container is separate from or independent of trailer components or trailer assembly. The illustration of FIG. 1 shows an example of the vertically collapsible container attached to, or otherwise integrated with, trailer assembly components. In one example of the self-erecting collapsible container portion, the frame assembly is attached to a trailer assembly.

In one example, the frame assembly of the vertically collapsible container is load bearing, enabling vertical stacking of containers in either the expanded or the collapsed positions. In one example of the self-erecting collapsible container portion, the frame assembly is pre-engineered to be capable of bearing a load when in the collapsed position. In one example the cover supports close to, or more, the same weight as a standard flatbed semi-trailer. In one example, the container supports the maximum stack limits that a normal 40 foot or 20 foot shipping container can support. In one example, the container portion supports placing one or more trailers on the top of the container, for example, a trailer bearing a collapsed container carries a trailer on the top of the collapsed container.

FIG. 2 illustrates a side view of an example of the vertically collapsible trailer 1 with its container in an extended position. In FIG. 2, the near retractable side wall 6 is shown in the closed position. In the open position, in one example, side wall 6 is stowed in a receptacle 61 in frame member 3 (FIG. 11). In this example, side wall 6 rolls up to provide an opening into cargo space 1018 (FIG. 1). In one example, receptacle 61 is disposed in an alternate rectangular frame member, such as, for example, lowermost frame member 2. In that example, side wall 6 rolls down to provide opening into cargo space 1018 (FIG. 1).

As in FIG. 1, FIG. 2 shows location of retractable end wall sides 7, 8 and articulated vertical frame members 9, 10. Rear retractable end wall 7 retracts into receptacle member 71 (FIG. 1). In like manner, rear retractable end wall 8 retracts into receptacle member 81 (FIG. 1).

Other components are shown in the illustrated example of FIG. 2 to show relative positioning and arrangement of the trailer-container components in the example where a trailer assembly or trailer components are combined with the collapsible container cargo space. Rub rail 1022 is shown disposed along the length of the exterior of rectangular frame 3. In one example, railing disposed along the cargo trailer roof, or flatbed floor, allows for attachment of straps for securing cargo when the trailer is in the collapsed position. In one example, the railing contains stake pockets for the placement of side stakes for further securing of cargo. In one example, contains or also contains ratchet cylinders as well as, in one example, other devices for securing cargo as per the need of the user and, in one example, in accordance with the requirements set forth by the trucking regulatory agency where the trailer is being operated. In one example, contains or also contains winch straps as well as, in one example, other devices for securing cargo as per the need of the user and, in one example, in accordance with the requirements set forth by the trucking regulatory agency where the trailer is being operated.

In one example a twist lock corner casting 1020 is disposed in the corners of the upper rectangular frame 3. In one example, castings 1020 enable affixing a second container unto the top of frame 3. In one example, twist locks provision for the carrying of a 40-foot shipping container. In one example, castings are placed in different positions along the side of the trailer depending on the length of the trailer. In one example, additional castings are added, positioned and arranged, to accommodate two 20-foot shipping containers. In one example, castings are designed to contain a rising nub or, in one example, a rising twist lock.

In one example, twist locks to receive shipping containers are also disposed on the top/roof of the collapsible semi-truck trailer or container. A standard twist lock (ISO 1161 [1984], for example) attaches at the bottom of a container and the top of the one below it. The twist lock can be attached and removed via the sockets built into the container. In one example, the sockets are disposed on the upper most rectangular frame member (and lower most if being used as a shipping container) spaced at 20 foot and 40 foot increments to accommodate standard shipping containers, for example, if a user uses their own twist locks to attach them. In one example, at least one socket is disposed on the uppermost rectangular frame member, the at least one socket configured to receive a twist lock for receiving shipping containers. In a further example, the frame assembly is attached to a trailer assembly.

In one example, the twist lock corner castings are engineered for the carrying of a 40-foot shipping container via the use of twist locks. In one example, these castings are placed in different positions along the side of the trailer, depending on the length of the trailer. In one example, additional castings are added to accommodate two 20-foot shipping containers. In one example, these castings are engineered to contain a rising nub or, in one example, a rising twist lock. In one example, for the collapsible container used as a shipping container, castings are disposed on the lowermost rectangular frame member. This enables the bottom of the container to be attached to the top of another container, or floor of a trailer, or deck, or other structure designed for receiving containers.

In one example, Rear Tires and Tandem Axle 1006 are disposed under frame 2 toward the longitudinal rear portion of the container. Landing gear 1010 is disposed under frame 2 toward the longitudinal front third portion of the trailer. A king pin 1014 is shown disposed under frame 2, further towards the front portion of the trailer from landing gear 1010. A spare tire compartment 1008 is disposed under frame 2, midway between rear tires 1006 and landing gear 1010. A rear bumper 1004 is disposed on the longitudinal rear end of the container-trailer combination. A port 1016 for electrical and air connections are disposed on the longitudinal front end of the container-trailer combination.

In one example, forklift slots 1003 are disposed on the uppermost or top frame 3. In this example, a forklift or other external lifting device engage the slots. In this way, the container or container-trailer combination can be extended or collapsed using an external lifting means, separate from or in addition to the lifting means provided by the container or container-trailer combination. In one example, two slots on either side of the trailer are available for raising and lowering the container-trailer by the use of a forklift, for example, no power source is available or in the event of a failure of the mechanical lifting mechanism.

In one example, twist-lock corner castings 1020 are used to extend or collapse using an external lifting means, separate from or in addition to the lifting means provided by the container or container-trailer combination.

In one example, a spreader or crane (e.g., by one of various devices such as crane wire, bar, hook systems that are used globally to lift a container off the ground) use castings 1020, which in turn raise or lower the collapsible container portion. In one example, in case of a failure of the lifting mechanism, the lifting and locking mechanisms are overridden and operated either manually or automatically to allow for the use of an external lifting mechanism.

In one example, rub rails 1022 are used to extend or collapse using an external lifting means, separate from or in addition to the lifting means provided by the container or container-trailer combination.

In one example, top member 31 is disposed on the uppermost portion of top frame 3, forming a ceiling or roof. In one example, top member 31 forms a supporting structural floor on top of collapsible container portion of trailer 1. In one example, top member 31 forms a cargo trailer roof. In one example, top member 31 forms a flatbed floor. In one example, top member 31 is the top side of the cargo area that, in one example, in the collapsed position becomes the floor of the flatbed trailer allowing for the transportation of larger items, shipping containers, and/or other loads. In one example, top member 31 supports as closely as possible the weight that a standard flatbed trailer can support. In one example, a refrigeration or air conditioning unit is attached to this top member.

FIG. 3 illustrates a side view of an example of the vertically collapsible trailer 1′ in collapsed position.

In FIG. 3, the near retractable side wall 6′ is retracted and stowed into its receptacle 61 (shown in FIG. 11). Rear collapsible vertical frame 9′ in now in a collapsed position, resting behind side wall 6′ in this view. In a like manner, front collapsible vertical frame 10′ in now in a collapsed position, resting behind side wall 6′ in this view (shown in FIG. 8).

In one example, locking mechanisms 1012 (shown in FIG. 1) secure frame 2 to frame 3 when in the collapsed position.

In one example, forklift slots 1003 are disposed on the uppermost or top frame 3. In this example, a forklift or other external lifting device provides an external means for lifting or collapsing the collapsible frame. In this way, the container or container-trailer combination can be extended or collapsed using an external lifting means, separate from or in addition to the lifting means provided by the container or container-trailer combination.

Other components are shown in the illustrated example of FIG. 3 to show relative positioning and arrangement of the trailer-container components in the example where a trailer assembly or trailer components are combined with the collapsible container cargo space. Rub rail 1022 is shown disposed along the length of the exterior of rectangular frame 3. In one example, a twist lock corner casting 1020 is disposed in the corners of the upper rectangular frame 3. In one example, castings 1020 enable affixing a second container unto the top of frame 3. Rear Tires and Tandem Axle 1006 are disposed under frame 2 toward the longitudinal rear portion of the container. Landing gear 1010 are disposed under frame 2 toward the longitudinal front third portion of the trailer. A king pin 1014 is shown disposed under frame 2, further towards the front portion of the trailer from landing gear 1010. A spare tire compartment 1008 is disposed under frame 2, midway between rear tires 1006 and landing gear 1010. A rear bumper 1004 is disposed on the longitudinal rear end of the container-trailer combination.

In one example, top member 31 is disposed on the uppermost portion of top frame 3, forming a ceiling or roof. In one example, top member 31 forms a supporting structural floor on top of collapsible container portion of trailer 1′. In one example, top member 31 is configured to provide a platform surface for receiving additional loads. In one example, top member 31 receives one or more containers. In one example, top member 31 receives one or more collapsible containers. In one example, top member 31 receives one or more vertically collapsible containers as described herein. In one example, top member 31 receives a combination of containers and collapsible containers. In one example, top member 31 receives a trailer. In one example, top member 31 receives a vertically collapsible trailer.

In one example, a vertically collapsible container is configured for supporting additional vertically collapsible containers.

A rear bumper 1004 is disposed on the longitudinal rear end of the container-trailer combination. Rear lights 1026 are shown disposed on rear bumper 1004 under frame 2 as part of the trailer. Axle 1030 of Rear Tires and Tandem Axle 1006 (FIG. 1-3) is visible behind the rear bumper 1004 in this example.

FIG. 5 illustrates a rear end view of an example of the vertically collapsible trailer 1′ in collapsed position.

FIG. 5 shows location of retractable side wall sides 6′ and rolling sidewall barrel 11 in the side wall receptacles. In this example, the retracted side wall side members 6′ are stowed by rolling onto rolling sidewall barrel 11. In one example, long sidewall is disposed on both sides of trailer which, in one example, utilizes a slatted wall which can roll either, in one example, upwards or, in one example, downwards into a barrel. In one example, cylindrical rolling mechanism is disposed into which the sidewall will roll into when converting into the collapsed position and out of when being expanded. In one example, the barrel may be on the upper end of the side wall or, in one example, the lower and the sidewall will roll upwards or downwards accordingly.

As frame 3 is lowered towards frame 2, several wall and vertical frame components which are deployed in the raised position are now stowed in the remaining space between the bottom and the top frame members.

In one example, a side wall member 602 is affixed on the exterior side of bottom frame 2.

Rear retractable end wall 7′ is refracted into its respective receptacle member.

In one example, door locking mechanism 1024 is disposed on retractable end wall 7′ to secure end wall 7′ to frame 2.

Other components are shown in the illustrated example of FIG. 5 to show relative positioning and arrangement of the trailer-container components in the example where a trailer assembly or trailer components are combined with the collapsed container cargo space. Rub rail 1022 is shown disposed along the length of the exterior of rectangular frame 3.

FIG. 6 illustrates a 3-D perspective view from forward end corner of an example of the vertically collapsible trailer 1″ in a partially collapsed position, with cut away of the near side wall 6″. The cut away enables viewing of the enclosed cargo space 1018 and cargo space floor 21.

In one example, the cargo space floor supports the cargo stored while the trailer is being used in the expanded mode. In one example, while the trailer is in the collapsed mode, this floor will be inaccessible.

Forward Collapsible Vertical Frame 10″ in this example is shown in a partially collapsed position to show the action of stowing the vertical frame members 1001, 1002 as top frame 3 is lowered towards bottom frame 2. In one example, the folding portion of the frame on the forward end of the trailer has folded inwards as the trailer goes to the collapsed position. To accomplish this, in one example, vertical frame assembly 10″ includes two vertical members 1001, 1002 attached by a hinge 106 that is positioned and arranged to enable the two members to articulate. In one example, the frame members 1001, 1002 of frame assembly 10″ are square or rectangular or polygon posts of desired length, the square or rectangular or polygon shape in the cross section. The vertical members 1001, 1002 rotate relative to each other about hinge 106, enabling an external side of each of members 1001, 1002 to approach each other. As members 1001, 1002 articulate about hinge 106, the members rotate from a vertical position to a more horizontal position.

In one example, an upper hinge on each side of the trailer frame allows for the collapsing of the container portion of trailer. Thus the upper hinges provide for the folding of the forward and after frames of the container/trailer.

The top of the vertical frame assembly 10″ is attached by a hinge 104 to top frame 3. In one example, these upper folding hinges enable folding of the forward and after Frames of the trailer.

In one example, motorized components are used for the mechanical lifting mechanism. In examples, this motor may vary in size, location, and type of fuel and power depending on the type of lifting mechanism that is used. In one example the motorized components are mounted under the trailer frame.

Further examples to summarize and illustrate are provided. In one example, the frame assembly is capable of bearing a load when in the collapsed position. In one example, the container conforms to international standards of size, shape and weight requirements set forth for shipping containers. In one example, the frame assembly is attached to a trailer assembly meeting the standards set forth by the trucking regulatory agency in which the trailer is operating. In one example, the container when in the collapsed position is capable of being used as a Flat Rack container.

In one example of the self-erecting collapsible container, the frame assembly is attached to a railcar assembly (“freight car” or “goods wagon”) for transportation of goods via railway, in one example, meeting the standards set forth by the railroad regulatory agency in which the railcar is operating. The Federal Railroad Administration (FRA), for example, regulates the U.S. railroads. In one example, the container conforms to Mexico standards. In one example, the container conforms to Canada standards.

In one example of the self-erecting collapsible container, the frame assembly is attached to a box truck assembly, in one example, meeting the standards set forth by the regulatory agency in which the truck is operating. A box truck, in examples, is also known as a cube truck, cube van, box van, or straight truck, is a truck with a cuboid-shaped cargo area. Box trucks currently typically range in size 4 to 7 meters in length, with smaller or larger sizes existing, but currently being rare in North America. Box trucks usually have a garage door-like rear door that rolls up. On some box trucks, the cargo area is accessible from the cab through a small door. Box trucks currently are usually used by companies that need to haul appliances or furniture. They are also used as moving trucks which can be rented from companies. In the U.S., the Department of Transportation regulates their specifications.

In one example of the self-erecting collapsible container, the frame assembly is attached to a personal trailer assembly to be hitched to a personal vehicle, in one example, meeting the standards set forth by the regulatory agency in which the trailer is operating. There are a few different types of “personal trailers”. In the U.S., these also currently fall under the DOT's regulations. For example, a full-trailer is the U.S. term for a freight trailer supported by front and rear axles and pulled by a drawbar. In Europe, this is known as an “A-Frame drawbar trailer”. A full-trailer is 96 or 102 in (2,438 or 2,591 mm) wide and 35 or 40 ft (10.67 or 12.19 m) long. In another example, a “close-coupled” trailer is fitted with a rigid towbar which projects from its front and hooks onto a hook on the tractor. It does not pivot as a drawbar does. For a “ball and socket trailer”, a trailer coupler is used to secure the trailer to the towing vehicle. The trailer coupler attaches to the trailer ball. This forms a ball and socket connection to allow for relative movement between the towing vehicle and trailer while towing over uneven road surfaces. “Fifthwheel and Goose neck trailers” are available for loads between 10,000 and 30,000 pounds. They are used for larger trailers and provide considerably more stability than does a traditional hitch. Both styles have trailers attach to a coupler mounted above the axle within the bed of the tow vehicle such as a flat deck or pickup truck. In one example, the personal trailer is a full-trailer. In one example, the personal trailer is an A-Frame drawback trailer. In one example, the personal trailer is a close-coupled trailer. In one example, the personal trailer is a ball-and-socket trailer. In one example, the personal trailer is a fifth-wheel trailer. In one example, the personal trailer is a goose-neck trailer. In one example, the trailer and collapsible container are configured for the container to be removable from the trailer. In one example, the collapsible container is integral to the trailer.

In one example, end walls are positioned and arranged to fold in the inward direction.

In one example, a vertical height locking mechanism is attached to relieve the scissor jack when in the extended (full-vertical) position.

In one example, the top/roof of the collapsible semi-truck trailer has a risible “nub” or risible twist lock to receive a bottom socket of a shipping container, in one example, enabling a shipping container to ride on top of the collapsed flat bed and locked in place.

In one example, sockets for twist locks to receive shipping containers are also disposed on the top/roof of the collapsible semi-truck trailer.

In one example, the frame assembly is attached to a box truck assembly meeting the standards set forth by the regulatory agency in which the truck is operating. In one example, a locking mechanism is included to lock the frame assembly in place when in the collapsed position.

In one example, one or more of the side or end walls is able to open as a door for access to the cargo space in the raised position.

In one example, a refrigeration unit is attached temporarily or permanently to move temperature sensitive cargoes. In one example, the frame assembly is configured to receive a refrigeration unit. In one example, a refrigeration unit is attached to the forward rolling door. In one example, the unit is attached in such a manner that it resides in the space where the part of the door that stays attached while it is rolling up or down is attached to the refrigeration unit and not directly on the top or bottom frame. In one example, a refrigeration unit disposed outside of a perimeter of the frame assembly. In one example, a refrigeration unit disposed within the frame assembly.

In one example, a GPS and communication system is attached to the container or trailer assembly. In one example, the GPS is disposed within the frame assembly. In one example, an identification system is attached to the container or trailer assembly. In one example, the identification system is disposed within the frame assembly. In one example, an RFID system is disposed on or within the container.

Operation.

In one example, one or more containers are stacked on a transportation vehicle, enabling one vehicle to move more than one container at a time. In one example, a trailer with a vertically collapsible container has one or more containers placed on top of the vertically collapsible container, in one example, with the vertically collapsible container in the collapsed position. In one example, the vertically collapsible container is integrated into the bed of the trailer. In one example, the vertically collapsible container is attached to the trailer, but is removable from the trailer. In one example, two or more collapsible containers are placed, one on top of the other, on a flat bed trailer. In one example, non-collapsible containers are stacked along with one or more collapsible containers. In one example, corner castings are disposed on the containers, positioned and arranged so that the containers are removably affixed to one another when stacked. In one example, a combination of 20-foot and 40-foot containers are positioned and arranged to stack on one another, for example, two 20-foot containers end-to-end stacked on or under either a 40-foot container or two other 20-foot containers that are also placed end-to-end. In one example, one or more of the stacked containers is a vertically collapsible container in a collapsed position. In one example, the vertically collapsible container(s) is described in one of the examples disclosed herein.
